How much water would I add to a 50percent solution of H2O2 to make 500 ml of 3percent H2O2?

To make a 500 ml solution of 3% H2O2 from a 50% solution, you would need to dilute the 50% solution with water. You would add 325 ml of water to 175 ml of the 50% H2O2 solution to achieve a final volume of 500 ml with a concentration of 3% H2O2.


How much is 500 cc's of hydrogen peroxide?

500 cc's of hydrogen peroxide is equivalent to 500 milliliters. Hydrogen peroxide has a density of 1.5 g/ml, so 500 ml would weigh approximately 750 grams.


When A dry soil sample has a volume of 500 mL After 400 mL of water are added to the soil the soil becomes saturated with 150 mL of surface water left on top What is the porosity of the soil?

Porosity is calculated by dividing the volume of voids (pores) by the total volume. In this case, the volume of voids is the difference between the volume of water added and the volume left on top of the saturated soil (400 mL - 150 mL = 250 mL). The total volume is the sum of the dry soil volume and the water added (500 mL + 400 mL = 900 mL). Therefore, the porosity of the soil is 250 mL / 900 mL, which is approximately 0.28 or 28%.


What is a 1mm of rain event?

1mm of rain is actually water volume of 1lt per 1m2 of surface, 1mm=1lt/1m2 explanation: Simply convert 1lt to 1000 ml. Since 1ml=1cm3 and 1cm=0.01m=10-2m then 1cm3 = 10-6m3 this means that 1lt=1000ml=1000cm3 = 1000 x 10-6m3= 10-3m3 So 1lt/1m2 from the above is 10-3m3/1m2= 10-3m = 1mm. I hope that it is not complicated.


Indicate the concentration of each ion present in the solution formed by mixing the following 15.0 mL of 0.260 M Na2SO4 and 27.2 mL of 0.200 M KCl Na K SO4 2 CL?

The final volume after mixing is 42.2 mL. To find the concentrations of each ion in the final solution: [Na+] = (0.260 M * 15.0 mL + 0) / 42.2 mL [K+] = (0 + 0.200 M * 27.2 mL) / 42.2 mL [SO4^2-] = (0.260 M * 15.0 mL) / 42.2 mL [Cl-] = (0.200 M * 27.2 mL) / 42.2 mL Calculate each concentration using these formulas.
